Chemistry: Neutralisation & Byproducts

Introduction

• This experiment has several aims:
• It shows how an acid and a base react to form salt and water.
• It shows how this can lead to the formation of a soluble salt.
• It shows how the soluble salt solution can be dried to obtain a pure, crystalline sample of the salt.
• It shows how a seed crystal can be grown by placing it in a concentrated soluble salt solution.
